In suspected herpes simplex encephalitis, what is the most critical initial management step?

• A. Await PCR results before starting therapy.
• B. Start broad-spectrum antibiotics only.
• C. Start corticosteroids immediately.
• D. Initiate intravenous acyclovir as soon as HSV encephalitis is suspected.

Answer: (D)

HSV encephalitis is a medical emergency, and time matters. Starting intravenous acyclovir right away, as soon as HSV encephalitis is suspected, targets the likely cause and significantly improves survival and neurological outcomes. Delaying therapy for PCR confirmation can allow the disease to progress, increasing morbidity and mortality. Corticosteroids aren’t the standard initial treatment here and antibiotics alone won’t address the viral infection. So the best initial step is to begin IV acyclovir immediately while you pursue diagnostic confirmation with imaging and CSF testing.
